Urban Evolution: One Central Park's Innovative Approach to Sustainable Architecture and Urban Growth

2023-08-30T19:32:00.000+00:00

In response to the current shortage of 300,000 homes across the nation, the Australian government extends an invitation for foreign real estate investment.

One Central Park, situated in Sydney, stands as a tangible manifestation of urban expansion. This project challenges the customary paradigm of favoring cost-effective, expedient ventures. It does so by leveraging three key elements: the weight of political influence, the preference of international investors for exceptional architecture, and the growing appetite for unique design. These factors converge to distinguish the project. Classified as a "State Significant Development," it enjoys the authority of the Minister of Planning for endorsement and serves as a yardstick for excellence within the public's perspective.

One Central Park mitigates its cooling energy load by employing an innovative system of linear slab-edge planters spanning five kilometers. These planters double as permanent shading shelves, effectively diminishing thermal impact within the apartments by approximately 20%. The plant foliage further enhances shading. Another significant shading source is the building's vegetation itself. This approach stands in contrast to conventional mechanical shades. The vegetation also plays a role in capturing carbon dioxide, emitting oxygen, and minimizing heat reflection, making it an environmentally friendly alternative.

The development's magnitude enables the implementation of large-scale solutions. It incorporates a 30-MW central thermal plant (CTP), a 2-MW tri-generation system, and a 1-ML/day blackwater treatment plant. The recovered thermal energy and power contribute to enhanced energy efficiency, while recycled water finds uses in thermal plant operations, irrigation, and residential needs. This planning strategy aligns with the Green Building Council of Australia's (GBCA) targets outlined in the Green Star rating system.

Traditional high-rises in Sydney's climate have a history of poor energy performance, leading to a reevaluation of design criteria. Consequently, One Central Park earns a rating of five under the Green Star system. This achievement underscores the realization that compliance alone would not have a substantial impact on public perception.

Strategic urban planning decisions, such as high-density construction in strategic locations, often go unnoticed. However, they play a pivotal role in sustainable design. The challenge lies in effectively conveying the significance of mitigating an invisible gas like CO2. The inherent invisibility of CO2 presents difficulties in translating its importance into architectural design. As a result, there exists a significant disparity between the idea of "green" buildings and their actual execution. The common association of green roofs and parks with sustainability is somewhat misleading, accounting for only a small portion of Green Star credits.

Distinguishing a zero-net-energy project from energy-inefficient neighboring structures can be challenging without context or expertise. To bridge the gap between environmental commitment and visible architecture, a broader design approach is essential. This involves going beyond mere checklist compliance and devising innovative technical solutions that may not receive immediate recognition but significantly enhance performance beyond standard requirements.

One Central Park effectively employs two innovative technologies, hydroponics and heliostats. These technologies are deeply integrated into its design and infrastructure, with a specific focus on site-specific deployment. Hydroponics facilitates the cultivation of plants on tower façades, utilizing recycled water from the blackwater treatment plant. Heliostats redirect direct sunlight into shaded areas of the development, catering to lighting and heating needs. These technologies, while previously experimental, have matured into practical methods for sustainable agriculture and energy generation.

The central focal point of the master plan is a public park that extends into smaller green spaces within individual developments. This park symbolizes the commitment to sustainable design, providing much-needed public recreation areas. Creating this park necessitates elevating some building mass off the ground and concentrating it along Broadway on the north border of the site. This configuration prevents overshadowing of the neighboring Chippendale residential area. However, it poses the challenge of obstructing park visibility from the city's main approach and casting shadows with tall buildings.

The new park, while smaller than Sydney's major parks, holds significance for local residents. The primary design challenge is to make this small neighborhood park conspicuous on a citywide scale. The approach involves integrating vegetation into the tower façades to make it visible from afar. The park's design addresses two distinct adjacent neighborhoods. The northern, eastern, and western sides feature a continuous veil-like appearance with green walls and planter bands. This façade faces the inner-city campus and busy traffic of Broadway. On the southern side, facing the Chippendale residential area, the park takes the form of planted plateaus and scattered puzzle pieces, adding texture and depth.

Tall massing along the north side of the site brings two challenges: shadows from towers and lack of light within the podium block. The solution involves breaking the volume into shorter and taller towers on a five-story podium. Sun-tracking heliostats redirect sunlight to reflectors on a cantilever off the taller tower, directing light into the atrium and overshadowed areas. Motion controls adjust the heliostats' orientation to optimize brightness and warmth, creating a dynamic interplay of light across the site. LED lights on reflector facets form an urban chandelier at night, resembling water reflections

One Central Park adheres to Green Star standards, emphasizing urban density, parks, and sustainable strategies. It incorporates hydroponics and heliostats into its design, with a focus on performance, visibility, and clean energy. This development sets a precedent for future projects, enhancing urban life and sustainable architecture. Pictures (MDRX, Bobarc, Sardaka)

Exploring Vitruvius' Influence on Architectural Styles, Orders, Proportion, and Geometry

2023-08-18T20:01:00.002+00:00

In the world of architecture, the works of Vitruvius stand as timeless pillars of knowledge. Marcus Vitruvius Pollio, a Roman architect and engineer during the 1st century BC, penned down his thoughts on architecture in his monumental work, "De Architectura" (Ten Books on Architecture). This ancient treatise remains a cornerstone for understanding architectural principles, encompassing topics such as architectural styles, orders, proportion, and geometry.

Vitruvius believed that architecture should encompass three essential qualities: firmness, commodity, and delight. This triad forms the basis for his exploration of architectural styles and orders. He classified buildings into three styles: Doric, Ionic, and Corinthian. Each style had its own distinct characteristics, reflecting the cultural values and aesthetics of the time. Vitruvius also introduced the concept of architectural orders - systems of columns and entablatures that served as the building blocks of classical architecture. The Doric, Ionic, and Corinthian orders were aligned with the three styles, each carrying its own unique symbolism and appeal.

Proportion was another key aspect emphasized by Vitruvius. He believed that harmony in architecture could be achieved through proportionate relationships, which he often related to musical ratios. His writings highlighted the importance of balancing dimensions, ensuring that various parts of a building were in harmonious relation to one another. Vitruvius' insights into proportion guided architects in creating visually appealing and structurally sound designs.

Geometry played a pivotal role in Vitruvius' architectural philosophy. He understood geometry as the foundation of architectural planning and construction. His writings revealed an understanding of geometry's role in aligning structures with the principles of symmetry and balance. This not only enhanced the aesthetic appeal of buildings but also contributed to their stability and functionality.
Despite being written over two thousand years ago, Vitruvius' teachings continue to resonate with architects and designers today. His emphasis on harmony, proportion, and geometry serves as a timeless guide in achieving architectural excellence. Modern architects draw inspiration from his writings to create structures that seamlessly blend form and function, all while paying homage to the historical legacy of classical architecture.

In conclusion, Vitruvius' writings on architectural styles, orders, proportion, and geometry have left an indelible mark on the world of architecture. His treatise "De Architectura" remains a revered source of wisdom for architects, reminding them that the principles of harmony and balance transcend time, shaping the way we perceive and construct the built environment.

The Dance of Light: Fireflies' Natural Brilliance vs. Human-Made Glow

2023-08-18T19:14:00.000+00:00

In the ethereal realm of luminescence, where nature and science intertwine, few phenomena captivate the imagination like the flickering glow of fireflies. These enchanting insects, with their nocturnal ballet of light, showcase a level of efficiency that humbles even the most advanced human-made illumination systems.

Fireflies, members of the Lampyridae family, have perfected the art of bioluminescence. Their intricate light-producing mechanism begins with a specialized organ called the lantern, located in their abdomens. Here, a chemical reaction takes place between luciferase enzymes and oxygen, resulting in the emission of light without generating any heat – a remarkable feat of efficiency.

Contrast this with human-created light sources, where conventional incandescent bulbs waste a significant portion of energy as heat. While fluorescent and LED bulbs offer improved efficiency, they still rely on electricity to stimulate photons, creating light with a certain degree of loss.

The firefly's elegant system not only conserves energy but also produces a specific wavelength of light that maximizes visibility and minimizes disruption to their surroundings. This natural adaptation is in stark contrast to human-made lighting, which often struggles to balance efficiency with light pollution and disruption of circadian rhythms.

Moreover, fireflies' ability to synchronize their flashes in a mesmerizing display holds lessons for efficient network communication in the digital age. Each flash contains a unique pattern, allowing these insects to identify their peers amidst the darkness. This efficient, low-energy communication strategy contrasts with our complex, power-hungry digital networks.

As we marvel at fireflies' luminous poetry, we are reminded of the elegance of nature's design and the opportunities it presents for human innovation. Researchers and engineers look to these creatures for inspiration in developing sustainable, energy-efficient lighting systems. The quest for biomimicry – emulating nature's genius – continues, with the aim of creating a greener, more efficient future.

In the end, the fireflies' radiant dance serves as a humbling reminder of the brilliance nature has achieved. As we strive to match their efficiency, we find ourselves drawn to the intricacies of their biology, hoping to harness their wisdom to illuminate not just our homes but also our path towards a brighter, more sustainable future.

The Eco Home Zero Carbon Footprint

2008-12-28T11:32:00.006+00:00

Eco House, residential villa, Benahavis, Spain, 2009

It is called The Eco Home, it is 7000 square feet with a zero carbon footprint and almost zero operating costs. Diseño Earle is an international architecture firm known for unique, and often ecologically minded, projects.
With this beautiful work Diseño Earle set a good standard in the world of Green House. This project will be built in Southern Spain by 2009, with 75% less waste and will operate 80% more efficiently than a similar sized home.

This is one amazing eco-house with the key environmental friendly aspect being the massive solar panels built into the wing like roof. The angle allows the roof integrated solar panels to sit at the optimum angle for solar energy harvesting. The roof also creates a space around the building exterior where thermal air currents are created. But the Diseño Earle team didn’t stop there, the house also features a rainwater reclamation system, grey water recycling, radiant heating system powered by the solar panels, geothermal energy for back-up cooling and heating, low VOC paints, LED lights, environmentally-sensitive smart glass and abundant natural lighting, and energy and water efficient appliances.

The modern, glass filled design allows plenty of natural light into living spaces, while a natural, saline pool helps keeps chemicals out. The building stores grey water in holding tanks in the basement, and features a rainwater harvesting system to manage and conserve water. The rooftop photovoltaics supply electricity to a radiant floor heating system that works in tandem with the natural ventilation of the building which retains and removes heat by natural thermal draws throughout the structure. A geoexchange system provides backup heating and cooling.

Green investment tax credit Renewed by the congress

2008-12-28T10:36:00.002+00:00

Renewable energy businesses are breathing a sigh of relief today as the extension of the production and investment tax credits that benefit their industries were approved by Congress as part of the $700 billion bail-out package for the financial industry.

It renewed and broadened a set of tax credits for wind and solar power, geothermal, tidal energy, and more. The move did little to prop up eco-energy stocks, which have followed oil prices down. But the news did send a positive jolt to one of the economy's darkest sectors: homebuilding. Or, more specifically, solar-powered homes. Consumers recognize that green homes "save money month in, month out," says Rick Andreen, president of Shea Homes Active Lifestyles Communities in Scottsdale, Ariz.

Aspiring buyers of green homes will benefit. The solar investment tax credit provisions will extend for eight years the 30 percent tax credit for both residential and commercial solar installations. A buyer who installs a typical $25,000 solar panel system on his roof will get $7,500 in income tax credits, up from $2,000 under the old standard. How long that investment takes to pay off will depend on local rules and utility rates. In markets with the most costly power, such as California, Connecticut, and New Jersey, the pretax compound rate of return on a typical home solar system will be better than 15% per year, says Andy Black, chief executive of OnGrid Solar, an industry research firm.

The fresh credits may mark a turning point for solar-powered homes. During the housing boom, when mortgages and energy were both cheap, green power was not a hot option; typical home buyers preferred granite countertops to solar panels. But even before the subprime crash, builders began to see rising interest in sun-powered dwellings. Ryness Co., which compiles sales data for homebuilders, found in a recent survey that homes with solar systems were outselling others by as much as 2:1 in 13 California communities.

ZERO ENERGY MEDIA WALL

2008-12-27T12:55:00.010+00:00

GreenPix designed by Simone Giostra & Parners and the Arup engineering corporation is a groundbreaking project applying sustainable and digital media technology to the curtain wall of Xicui entertainment complex in Beijing, near the site of the 2008 Olympic Games. Featuring the largest color LED display worldwide and the first photovoltaic system integrated into a glass curtain wall in China, the building performs as a self-sufficient organic system, harvesting solar energy by day and using it to illuminate the screen after dark, mirroring a day’s climatic cycle

The wall’s low-resolution will emphasize the abstracted image of the work that will be shown. This spectacular screen which offers stunning projections will release no carbon into the atmosphere thanks to the sustainable technology, which corresponds directly with China’s political wish to appear ecological.

Schueco and SunWays, Giostra and Arup developed a new technology for laminating photovoltaic cells in a glass curtain wall and oversaw the production of the first glass solar panels by Chinese manufacturer SunTech.

The polycrystalline photovoltaic cells are laminated within the glass of the curtain wall and placed with changing density on the entire building’s skin. The density pattern increases building’s performance, allowing natural light when required by interior program, while reducing heat gain and transforming excessive solar radiation into energy for the media wall. This giant screen of 2,200 m² absorbs energy during the day and generates light from the power during the evening.

Solar cells facade of a Manchester skyscraper

2008-12-24T11:46:00.010+00:00

The facade of this Manchester skyscraper (owned by CIS, an insurance company) was original covered with small mosaic tiles, but after only six months, they began to detach and fall.

A solution was needed, and a company called solarcentury came up with a clever idea replacing the failing tiles with solar cells. Not only do the solar cells provide a weatherproof barrier, they also generate about 390kW of power for the building. In total, 7,244 Sharp 80W modules are used to cover the entire service tower (but apparently only 4898 of these modules are "live" the others are "dummy modules" — strange). The building also has 24 wind turbines on the roof, which provide 10% of the total power used by the building. (from MetaEfficient.com)

There’s even a peregrine falcon nesting box up on top with a camera installed to keep an eye on the birds’ comings and goings – this isn’t just a normal office block, this tower could soon be an ecotourism hotspot!

Synthetic slates

2008-12-24T11:31:00.008+00:00

The company Polco developed a slate of synthetic roofing, Polyard®, having same aspect as natural slate while being twice lighter and resisting better to the bad weather. They are obtained by moulding of mix polyurethane / sand. Then, they are covered with an anti-UV film. Raw materials come from abundant resources as sand or renewable quickly as the castor oil used for the polyurethan synthesis. The manufacturing process is little energy-consuming. These slates are recyclable : once crushed, they are added at the raw material to produce new synthetic slates. This allows a less consumption in virgin raw materials.

The apparent face of slates is protected by a coating pigmented slate, hydrophobic, anti UV, and resistant to an aggressive environment : not cleared or tarnished effect, resistance to the hail, not stagnation of water. A polyard® plate contains the equivalent of 6 natural slates.

Polyard® slates benefit of an Atex (technical appreciation of experimentation) of the CSTB (scientific and technical center of building).

Eco wood By Exwood

2008-12-24T09:37:00.002+00:00

Exwood is an eco-friendly material, it looks, feels and has many of the same characteristics as wood. It can be worked in the same ways as wood with the same tools. Exwood is a composite material made from a combination of the waste organic fibre rice husk and PVC plastic.

Exwood is a truly eco positive material. Unlike many other wood alternatives Exwood is made from 50% rice husk as opposed to using wood powder and so has a true grain affect unlike many WPCs (wood plastic composites).

Exwood is a unique SPC (silicon plastic composite), it does not have the 'plastic' looking texture of WPC's but a mat wood like finish which is incredibly similar to natural wood.

In the past there existed two problems for such an eco-friendly wood-alternative; there wasn't any material that shared the same physical characteristics and workability as timber; and it was too expensive to create such a material.

After years of research and analysis, Exwood noted that mixed with rice husk, PVC was the base polymer whose characteristics were closest to the requirements in terms of mechanical properties, resistance to atmospheric agents, workability and most importantly, price.

Exwood can be processed using conventional thermoplastic processes such as extrusion and injection moulding. Presently the technology enables the material to be made with over 50% (by weight) of organic fibre (rice husk) in the composite matrix.

Since the production of Exwood requires no virgin wood resource and does not contain any wood preservative, plus Exwood incorporates recycled plastic from post consumer window frames which would otherwise be sent to land fill, it is an environmentally superior material.

Exwood can negate much of the need for deforestation and requires effectively no maintenance, that is no varnishes, no paints, no thinners - no chemicals.

Wind Generator by Bil Becker

2008-12-23T17:26:00.005+00:00

Professor Bil Becker worked with Buckminster Fuller and has developed helical turbines which use centrifugal force to efficiently harness the power of the wind.

These compact turbines can be located on top of buildings, or attached to other parts of large structures like bridges.
Reasonably sized and modestly priced, the turbines may be used in urban locations. For many years, a fellow named Bil Becker has been hard at work developing his Aerotecture turbines. The turbines are elegant devices which incorporate both Savonius and Darrieus styles into one turbine.

There is no reason a city with its ample wind and sunshine, couldn’t generate all of its own power, helping people unplug from its addiction to nuclear power.

The advantages of these kinds of turbines are numerous. They are much more bird-friendly than typical bladed wind turbines. The bladed turbines become "invisible" to birds once they reach speeds of about 400 RPMs. At these speeds, the blades blur, and birds cannot see them. Becker's Aerotecture turbines are always visible, even at their highest speeds, which literally cannot exceed about 250 RPMs.

Mill Valley Straw-bale Residence By Arkin - Tilt Architects

2008-10-21T12:56:00.009+00:00

Arkin Tilt Architects is an award-winning firm specializing in energy and resource efficient design. This compact four-bedroom 1860 s.f. passive solar straw-bale home illustrates solutions to ecological living designed by this firm.

Although oriented on a north-south axis to maintain neighbor’s views, the interior temperature of the home stays within 5° of 68°F without additional heating or cooling. The roof is insulated with cellulose (recycled newspaper) insulation and sheathed with ‘Meadowood’ rye-grass straw-board. Straw-bale walls with PISE (sprayed-earth) finish are balanced by fiber-cement clad conventionally framed walls in appropriate locations (i.e. plumbing, bays and the high cupola walls).

A structural wall of exposed framing provides ample storage for books and art while dividing the living and sleeping areas. Bedrooms all feature bed-sized window bays, and two of the children’s bedrooms are separated with movable wall panels, adding further flexibility. Other ecological features include built-in composting and recycling (hatches in the backsplash allow recyclables to be placed in bins which are accessed from the outside), high efficiency lighting, Fire-slate countertops and many reused doors throughout the house.

Eco-Architecture - Second International Conference in Portugal

2008-10-21T11:34:00.006+00:00

The 2nd International Conference on Harmonisation between Architecture and Nature (Eco-Architecture) took place recently in the Algarve, Portugal, organised by the Wessex Institute of Technology of the UK.

Eco-Architecture provides design in harmony with nature, including its immediate environments. Decisions are taken on ecological grounds covering location, siting and orientation, as well as the well-informed choice of materials.

The conference papers were organised in a series of sessions as follows:

* Design with nature
* Design by passive systems
* Rehabilitation and adaptive re-use
* Ecological and cultural sensitivity
* Case studies
* Resource conservation and building technologies

Eco-Architecture makes every effort to minimise the use of energy at each stage of the building’s life cycle, including that embodied in the extraction and transportation of materials, their fabrication, their assembly into the building and ultimately the ease and value of their recycling when the building’s life is over. The design ought also to take into account the use of energy in building maintenance and changes in its use, not to mention its lighting, heating and cooling, particularly when the energy concerned involves the emission of greenhouse gases.

The development of eco-architecture is driven by the depletion of natural resources, especially fossil fuels and the need to preserve the balance of nature. The extensive use of steel and glass and the built-in problems of discomfort from solar over-heating and winter heat loss, has led to the widespread use of mechanical systems, which by careful design, could have been avoided in almost any climate.

this Conference on Harmonisation Between Architecture and Nature ought to be in harmony with nature, including its immediate environs. Eco-Architecture is providing imaginative and expressive solutions driven by a generation of highly creative designs. It has important cultural as well as architectural impacts.

Masdar Headquarters set a new paradigm

2008-06-23T15:03:00.005+00:00

Adrian Smith + Gordon Gill Architecture has won an international competition to design the Masdar Headquarters, the first building in the zero waste, zero carbon emission Masdar City outside of Abu Dhabi in United Arab Emirates. The Masdar Headquarters will be the first mixed-use positive energy building in the world. AS+GG worked with MEP engineers Environmental Systems Design and structural engineers Thornton Tomasetti on the design.

The roof is entirely covered by 1,4 million square feet (=130000 m2) solar panels. the roof covering a building is absolutely gigantic. The building will also have integrated wind turbines, solar-driven cooling and de-humidification will consumpt 70% less water than other building of its size. They decided to make the building process as green as possible by building the solar roof first - that way it alone will produce enough energy to power the rest of the construction. It’s very encouraging to see progress like this in the sustainable building field.

"Masdar Headquarters will set a new paradigm for the way buildings are designed, constructed and inhabited," said Gordon Gill, partner, AS+GG. "The project represents the perfect integration of architecture and engineering, resulting in a dynamic, inviting building that outperforms any other structure of its type in the world.". The building will cost over $300 million.

Orquideorama the trees growing together

2008-06-23T14:11:00.004+00:00

The town of Medellin, Colombia, got another architectural addition. An amazing botanical garden with a superstructure called Orquideorama. This steel and wood structure in an hexagonal shape extends through its organic shape. The renovation was done by Plan B architects and the idea was to make a structure that looks like trees growing together at the branches. A stunning study on structure and scale, the project unites the micro and macro worlds through an elegant synthesis of cellular and architectural forms. The plants situated beneath each trunk are sustained via rainwater collected by the petals, and are protected from the elements by the translucent pine wood weave that is sourced from reforested lands.

The project serves as a showroom, concert area and an exposition area. So beautiful.

Walking on the water

2008-02-25T21:04:00.004+00:00

What must have a boat house? There must be a boat, it should be a home to care for their environment, it has to be built with materials very different from the usual, and it must seem like a home.

Staffan Strindberg initiated the project for a specific customer but without a specific place, so he had to shape an imaginary place to start.

Through an expression of modern design and form, Villa Näckros has been developed to offer comfortable, exclusive water side living close to nature.

A residence with leading words as; sustainability, low maintenance, development of materials and building, care for the environment, low energy costs, identity.

Näckros Villa sits securely and stably in the water with its 165 ton constructed weight and is impervious to wind.

A Näckros Villa is constructed with material recycling potential as a starting point. New techniques and carefully chosen materials have resulted in a house that is extremely comfortable to live in and is in many parts recyclable.

Heating is provided by a pump, which draws heat from the surrounding water. Heat is distributed through the house through water bearing under floor heating. Two-way air ventilation can be found throughout the house. As far as possible, the house has been designed to meet demands in respect of both energy and environment.

A comfortable living and a lay-out that gives you the optimal feeling of the closeness to the water.

area : 178 sqm of living area, 30 sqm terrace close to the water and a 100sqm "garden" on the roof.

Achitect : Staffan Strindberg

Have you ever seen this building before ?

Probably not, in fact it is my project in the first semester (I'm in my third year of BA architecture). I use Kerkythea for the rendering which is very good and free. You have some comment ? Great...

The boulders house.

2008-02-23T22:50:00.005+00:00

The two-story house, of minimal 9-meter cubic proportions, was designed to be a habitable sculpture. Titus Bernhard, the architect used some 365 steel baskets, weighing 28 tones of dolomite stones. The entire house giving it a solid, medieval look. The steel and stone structure is placed in front of the brick shell insulation. The entire shell of the building is built under the steel baskets and is designed to act as a water-bearing layer.

The 28 tons of boulders have formed a kind of ecological shell for the building, buffering the heat in summer and the cold in winter. This way the consumption of energy is reduced to a minimum.

Architect : Titus Bernhard
